Quick Answers

So, is Xeon E3-1505M v6 better than Xeon E5-1630 v3?

It depends on what you want from the system. For gaming, Xeon E5-1630 v3 is ahead with a 8.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Xeon E3-1505M v6 pulls ahead with 0.3% better PassMark. Xeon E5-1630 v3 also has the bigger cache pool with 25% larger total L3 cache (10 MB vs 8 MB).

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Xeon E3-1505M v6 is the stronger fit. You are getting 0.3% better PassMark, backed by 4 cores and 8 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Xeon E3-1505M v6 is still the faster CPU overall, but Xeon E5-1630 v3 is easier to justify if budget matters more than peak performance. Xeon E3-1505M v6 comes in 16.7% more expensive on MSRP at $434 MSRP versus $372 MSRP, and it still gives you 0.3% better PassMark. The compromise is that Xeon E5-1630 v3 is still the better pure gaming CPU with a 8.6% average FPS lead across 50 shared CPU game tests in our data. Xeon E5-1630 v3 is also 16.4% better value on MSRP (19.9 vs 17.1 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

Which one is more future-proof for 2026 and beyond?

Xeon E3-1505M v6 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2014) and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
